ROSA Fresh 12.4 arrives with Linux 6.1.20 with MGLRU, improvements and more

ROSA Linux is a Linux distribution and operating system, developed by the Russian company LLC NTC IT ROSA

STC IT PINK recently announced the launch of the corrective version of "PINK Fresh 12.4«, this being the fourth corrective version of the 12.x branch that contains all changes and corrections for a year and a half platform development.

For those who are unaware of ROSA Fresh, they should know that this is a modern Russian Linux distribution, created by the community and legally available to everyone for free and whose source code of the system is published under the GPL license.

PINK originated as a fork of the now defunct Mandriva Linux distribution and has since been independently developed. The ROSA company was founded in early 2010 and released the first version of its operating system in December 2010. Initially, it targeted business users, but at the end of 2012 ROSA started its end-user oriented distribution, the DesktopFresh.

Main novelties of ROSA Fresh 12.4

In this new released version of ROSA Fresh 12.4, the package base has been updated, with which we can find the kernel of Linux 6.1.20 as the heart of this new release (note that the previously shipped 5.10 and 5.15 branches continue to be supported), besides that kernel 6.1 has MGLRU (Multi-Generation LRU) enabled by default.

MGLRU it is positioned as a superior alternative to the kernel's existing page retrieval code. This as such is an alternative LRU implementation that optimizes page fetching and improves performance under memory pressure. Page fetch decides the kernel's caching policy and memory overhead ability. It directly affects kswapd's CPU usage and memory efficiency.

Another change What stands out about the new version is that support for wired network cards has been improved Realtek based on RTL8111, RTL8168 and RTL8411 chips, for which added a separate operating system kernel module r8168, which is automatically used as the driver for these network cards, and support for these cards from the r8169 driver in the default Linux kernel 6.1 removed

In addition to this, it is also highlighted that new versions of update prompt and help console are proposed (termhelper) developed by the ROSA project and added support for installing on encrypted partitions without entering a password at boot

Also Additional updated drivers for Wi-Fi and Bluetooth are highlighted: Realtek 8188gu, 8192du, 8723du, 8812au, 8814au, 8821au, 8821cu, 8852au, 88x2bu, rtw89 (8852ae, 8852be, 8853ce)

Of the other changes that stand out of the new version:

  • Updated linux firmware package.
  • Added the rtk_btusb-firmware package to support additional hardware, mainly wireless cards.
  • Updated proprietary drivers for NVIDIA 340, 390, 470, 510, 515, 520, and 525 video cards.
  • The “sudo kroko-cli autoinstall” command can be used to select and install the required driver version.
  • Fixed a startup delay when installing to BTRFS without a separate /boot partition on ext2/3/4 (in such configurations, the functionality of saving the last loaded item to Grub is automatically disabled).
  • Problems with the "reboot" command have been fixed in the kickstart scripts.
